update

sunset update [path] [flags]

update hashes discovered files and reparses only files whose content changed since the cache entry. It always uses the cache and always writes summary output. It does not accept --detail, --no-cache, or --max-depth.

Flag	Default	Meaning
--output	<path>/.sunset/output	Destination directory.
--exclude	empty	Comma-separated filename or relative-path glob patterns.
--concurrency	CPU count	Maximum parallel parsers.
--quiet	false	Suppress normal progress output.

sunset update . --exclude "*_test.go" --quiet

An incremental index contains only newly parsed file metadata, not all cached files. Removed cache entries do not remove old per-file Markdown; see limitations.
